It isn't that simple. People with faster metabolisms burn calories faster,
and people with slow metabolisms burn calories more slowly. People respond
differently to different types of food too. Some people gain weight a lot
faster when they eat simple carbs, while others don't. If a person's body
goes into starvation mode from a restricted diet, the body will struggle to
hang onto every ounce of fat. People in that situation have a better chance
of losing weight if they eat *more.* When you eat also affects how calories
are burned. And so on.
While it is true that simple sugars (i.e. fructose) will cause insulin
spikes and therefore increased absorbtion, the premise is the same:
Once a calorie is stored, it doesn't matter where the calorie came from.
Eating *too much[1]* of anything will cause it to be stored as fat. Eat too
much fat and it gets stored as fat. Eat too much carbohydrate and it gets
stored as fat. Eat too much protein and it gets stored as fat.
For the general populace all it takes to lose weight, is to expend more
energy therefore burning calories. There are things[2] people can do that
have been found to use fat as the energy source rather than glucose, but all
it often takes for most people to lose weight is to just get off of their
fat asses and do *something* active
[1] - "Too Much" being defined as more than the body requires to meet the
demand for its quest toward homeostasis
[2] - As part of an exercise regimen, it has been reported that extended
periods (>45mins) of low intensity aerobics will utilize fat as its source
of energy.
